Trunking Question

Quick Trunk questions. It doesn't matter what the Access mode VLAN is if the port is trunking, correct?

Thanks, Pat.

Re: Trunking Question

You are correct. Access mode vlan doesnt matter.

Negotiation of Trunking: On

this is why the trunk will come up regardless.

Please rate answers you find useful.

Re: Trunking Question

Hi,

The operational mode is trunking, which means the switchport is indeed running in trunk mode, therefore the access vlan does not matter.

Operational Mode: trunk

Best regards,

Andras
